目的 探讨宝石能谱CT小肠造影在小肠病变诊断中的临床价值。方法 选取2013年1月至2017年1月我院经病理确诊的 小肠病变患者56例，均进行宝石能谱CT小肠造影检查，分析其影像学表现。结果 56例小肠病变患者均顺利完成CT 检查，其中小肠炎症性病变39例，包括小肠粘连性梗阻22例，克罗恩病10例，肠系膜血管血栓形成7例，小肠肿瘤 17例，包括腺癌9例，间质瘤5例，肠道淋巴瘤3例。结论 经宝石能谱CT检查，能清晰显示小肠粘膜、肠壁结构及系 膜血管解剖结构，能获得较好的图像质量。

Objective To investigate the clinical value of gem spectrum CT small bowel radiography in the diagnosis of small bowel diseases. Methods 56 cases of small intestinal lesions diagnosed by pathology in our hospital from January 2013 to January 2017 were selected and all of them were examined by gem spectrum CT small bowel radiography and analyzed the imaging findings. Results 56 cases of small intestinal lesions were successfully completed with CT examination, including 39 cases of intestinal inflammatory lesions, 22 cases of adhesion intestinal obstruction, 10 cases of Crohn's disease, 7 cases of mesenteric thrombosis, 17 cases of small intestinal tumor, 9 cases of adenocarcinoma, 5 cases of stromal tumors, and 3 cases of intestinal lymphoma. Conclusion The CT structure of the small intestine, the intestinal wall and the vascular anatomy of the mesentery can be clearly displayed and the better image quality can be obtained by the gem spectrum
